+ *
+ *     // register classes with namespaces
+ *     $loader->add('Symfony\Component', __DIR__.'/component');
+ *     $loader->add('Symfony',           __DIR__.'/framework');

+ *     $loader->register();

+ *     // to enable searching the include path (eg. for PEAR packages)
+ *     $loader->setUseIncludePath(true);
+ *
+ * In this example, if you try to use a class in the Symfony\Component
+ * namespace or one of its children (Symfony\Component\Console for instance),
+ * the autoloader will first look for the class under the component/
+ * directory, and it will then fallback to the framework/ directory if not
+ * found before giving up.
+ *
+ * This class is loosely based on the Symfony UniversalClassLoader.

+Message Headers
+===============
+
+Sometimes you'll want to add your own headers to a message or modify/remove
+headers that are already present. You work with the message's HeaderSet to do
+this.
+
+Header Basics
+-------------
+
+All MIME entities in Swift Mailer -- including the message itself -- store
+their headers in a single object called a HeaderSet. This HeaderSet is
+retrieved with the ``getHeaders()`` method.
+
+As mentioned in the previous chapter, everything that forms a part of a message
+in Swift Mailer is a MIME entity that is represented by an instance of
+``Swift_Mime_SimpleMimeEntity``. This includes -- most notably -- the message
+object itself, attachments, MIME parts and embedded images. Each of these MIME
+entities consists of a body and a set of headers that describe the body.
+
+For all of the "standard" headers in these MIME entities, such as the
+``Content-Type``, there are named methods for working with them, such as
+``setContentType()`` and ``getContentType()``. This is because headers are a
+moderately complex area of the library. Each header has a slightly different
+required structure that it must meet in order to comply with the standards that
+govern email (and that are checked by spam blockers etc).
+
+You fetch the HeaderSet from a MIME entity like so::
+
+    $message = new Swift_Message();
+
+    // Fetch the HeaderSet from a Message object
+    $headers = $message->getHeaders();
+
+    $attachment = Swift_Attachment::fromPath('document.pdf');
+
+    // Fetch the HeaderSet from an attachment object
+    $headers = $attachment->getHeaders();
+
+The job of the HeaderSet is to contain and manage instances of Header objects.
+Depending upon the MIME entity the HeaderSet came from, the contents of the
+HeaderSet will be different, since an attachment for example has a different
+set of headers to those in a message.
+
+You can find out what the HeaderSet contains with a quick loop, dumping out the
+names of the headers::
+
+    foreach ($headers->getAll() as $header) {
+      printf("%s<br />\n", $header->getFieldName());
+    }
+
+    /*
+    Content-Transfer-Encoding
+    Content-Type
+    MIME-Version
+    Date
+    Message-ID
+    From
+    Subject
+    To
+    */
+
+You can also dump out the rendered HeaderSet by calling its ``toString()``
+method::
+
+    echo $headers->toString();
+
+    /*
+    Message-ID: <1234869991.499a9ee7f1d5e@swift.generated>
+    Date: Tue, 17 Feb 2009 22:26:31 +1100
+    Subject: Awesome subject!
+    From: sender@example.org
+    To: recipient@example.org
+    MIME-Version: 1.0
+    Content-Type: text/plain; charset=utf-8
+    Content-Transfer-Encoding: quoted-printable
+    */
+
+Where the complexity comes in is when you want to modify an existing header.
+This complexity comes from the fact that each header can be of a slightly
+different type (such as a Date header, or a header that contains email
+addresses, or a header that has key-value parameters on it!). Each header in
+the HeaderSet is an instance of ``Swift_Mime_Header``. They all have common
+functionality, but knowing exactly what type of header you're working with will
+allow you a little more control.
+
+You can determine the type of header by comparing the return value of its
+``getFieldType()`` method with the constants ``TYPE_TEXT``,
+``TYPE_PARAMETERIZED``, ``TYPE_DATE``, ``TYPE_MAILBOX``, ``TYPE_ID`` and
+``TYPE_PATH`` which are defined in ``Swift_Mime_Header``::
+
+    foreach ($headers->getAll() as $header) {
+      switch ($header->getFieldType()) {
+        case Swift_Mime_Header::TYPE_TEXT: $type = 'text';
+          break;
+        case Swift_Mime_Header::TYPE_PARAMETERIZED: $type = 'parameterized';
+          break;
+        case Swift_Mime_Header::TYPE_MAILBOX: $type = 'mailbox';
+          break;
+        case Swift_Mime_Header::TYPE_DATE: $type = 'date';
+          break;
+        case Swift_Mime_Header::TYPE_ID: $type = 'ID';
+          break;
+        case Swift_Mime_Header::TYPE_PATH: $type = 'path';
+          break;
+      }
+      printf("%s: is a %s header<br />\n", $header->getFieldName(), $type);
+    }
+
+    /*
+    Content-Transfer-Encoding: is a text header
+    Content-Type: is a parameterized header
+    MIME-Version: is a text header
+    Date: is a date header
+    Message-ID: is a ID header
+    From: is a mailbox header
+    Subject: is a text header
+    To: is a mailbox header
+    */
+
+Headers can be removed from the set, modified within the set, or added to the
+set.
+
+The following sections show you how to work with the HeaderSet and explain the
+details of each implementation of ``Swift_Mime_Header`` that may exist within
+the HeaderSet.
+
+Header Types
+------------
+
+Because all headers are modeled on different data (dates, addresses, text!)
+there are different types of Header in Swift Mailer. Swift Mailer attempts to
+categorize all possible MIME headers into more general groups, defined by a
+small number of classes.
+
+Text Headers
+~~~~~~~~~~~~
+
+Text headers are the simplest type of Header. They contain textual information
+with no special information included within it -- for example the Subject
+header in a message.
+
+There's nothing particularly interesting about a text header, though it is
+probably the one you'd opt to use if you need to add a custom header to a
+message. It represents text just like you'd think it does. If the text contains
+characters that are not permitted in a message header (such as new lines, or
+non-ascii characters) then the header takes care of encoding the text so that
+it can be used.
+
+No header -- including text headers -- in Swift Mailer is vulnerable to
+header-injection attacks. Swift Mailer breaks any attempt at header injection
+by encoding the dangerous data into a non-dangerous form.
+
+It's easy to add a new text header to a HeaderSet. You do this by calling the
+HeaderSet's ``addTextHeader()`` method::
+
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addTextHeader('Your-Header-Name', 'the header value');
+
+Changing the value of an existing text header is done by calling it's
+``setValue()`` method::
+
+    $subject = $message->getHeaders()->get('Subject');
+    $subject->setValue('new subject');
+
+When output via ``toString()``, a text header produces something like the
+following::
+
+    $subject = $message->getHeaders()->get('Subject');
+    $subject->setValue('amazing subject line');
+    echo $subject->toString();
+
+    /*
+
+    Subject: amazing subject line
+
+    */
+
+If the header contains any characters that are outside of the US-ASCII range
+however, they will be encoded. This is nothing to be concerned about since mail
+clients will decode them back::
+
+    $subject = $message->getHeaders()->get('Subject');
+    $subject->setValue('contains – dash');
+    echo $subject->toString();
+
+    /*
+
+    Subject: contains =?utf-8?Q?=E2=80=93?= dash
+
+    */
+
+Parameterized Headers
+~~~~~~~~~~~~~~~~~~~~~
+
+Parameterized headers are text headers that contain key-value parameters
+following the textual content. The Content-Type header of a message is a
+parameterized header since it contains charset information after the content
+type.
+
+The parameterized header type is a special type of text header. It extends the
+text header by allowing additional information to follow it. All of the methods
+from text headers are available in addition to the methods described here.
+
+Adding a parameterized header to a HeaderSet is done by using the
+``addParameterizedHeader()`` method which takes a text value like
+``addTextHeader()`` but it also accepts an associative array of key-value
+parameters::
+
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addParameterizedHeader(
+      'Header-Name', 'header value',
+      ['foo' => 'bar']
+      );
+
+To change the text value of the header, call it's ``setValue()`` method just as
+you do with text headers.
+
+To change the parameters in the header, call the header's ``setParameters()``
+method or the ``setParameter()`` method (note the pluralization)::
+
+    $type = $message->getHeaders()->get('Content-Type');
+
+    // setParameters() takes an associative array
+    $type->setParameters([
+      'name' => 'file.txt',
+      'charset' => 'iso-8859-1'
+    ]);
+
+    // setParameter() takes two args for $key and $value
+    $type->setParameter('charset', 'iso-8859-1');
+
+When output via ``toString()``, a parameterized header produces something like
+the following::
+
+    $type = $message->getHeaders()->get('Content-Type');
+    $type->setValue('text/html');
+    $type->setParameter('charset', 'utf-8');
+
+    echo $type->toString();
+
+    /*
+
+    Content-Type: text/html; charset=utf-8
+
+    */
+
+If the header contains any characters that are outside of the US-ASCII range
+however, they will be encoded, just like they are for text headers. This is
+nothing to be concerned about since mail clients will decode them back.
+Likewise, if the parameters contain any non-ascii characters they will be
+encoded so that they can be transmitted safely::
+
+    $attachment = new Swift_Attachment();
+    $disp = $attachment->getHeaders()->get('Content-Disposition');
+    $disp->setValue('attachment');
+    $disp->setParameter('filename', 'report–may.pdf');
+    echo $disp->toString();
+
+    /*
+
+    Content-Disposition: attachment; filename*=utf-8''report%E2%80%93may.pdf
+
+    */
+
+Date Headers
+~~~~~~~~~~~~
+
+Date headers contains an RFC 2822 formatted date (i.e. what PHP's ``date('r')``
+returns). They are used anywhere a date or time is needed to be presented as a
+message header.
+
+The data on which a date header is modeled as a DateTimeImmutable object. The
+object is used to create a correctly structured RFC 2822 formatted date with
+timezone such as ``Tue, 17 Feb 2009 22:26:31 +1100``.
+
+The obvious place this header type is used is in the ``Date:`` header of the
+message itself.
+
+It's easy to add a new date header to a HeaderSet. You do this by calling the
+HeaderSet's ``addDateHeader()`` method::
+
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addDateHeader('Your-Header', new DateTimeImmutable('3 days ago'));
+
+Changing the value of an existing date header is done by calling it's
+``setDateTime()`` method::
+
+    $date = $message->getHeaders()->get('Date');
+    $date->setDateTime(new DateTimeImmutable());
+
+When output via ``toString()``, a date header produces something like the
+following::
+
+    $date = $message->getHeaders()->get('Date');
+    echo $date->toString();
+
+    /*
+
+    Date: Wed, 18 Feb 2009 13:35:02 +1100
+
+    */
+
+Mailbox (e-mail address) Headers
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Mailbox headers contain one or more email addresses, possibly with personalized
+names attached to them. The data on which they are modeled is represented by an
+associative array of email addresses and names.
+
+Mailbox headers are probably the most complex header type to understand in
+Swift Mailer because they accept their input as an array which can take various
+forms, as described in the previous chapter.
+
+All of the headers that contain e-mail addresses in a message -- with the
+exception of ``Return-Path:`` which has a stricter syntax -- use this header
+type. That is, ``To:``, ``From:`` etc.
+
+You add a new mailbox header to a HeaderSet by calling the HeaderSet's
+``addMailboxHeader()`` method::
+
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addMailboxHeader('Your-Header-Name', [
+          'person1@example.org' => 'Person Name One',
+          'person2@example.org',
+          'person3@example.org',
+          'person4@example.org' => 'Another named person'
+    ]);
+
+Changing the value of an existing mailbox header is done by calling it's
+``setNameAddresses()`` method::
+
+    $to = $message->getHeaders()->get('To');
+    $to->setNameAddresses([
+      'joe@example.org' => 'Joe Bloggs',
+      'john@example.org' => 'John Doe',
+      'no-name@example.org'
+    ]);
+
+If you don't wish to concern yourself with the complicated accepted input
+formats accepted by ``setNameAddresses()`` as described in the previous chapter
+and you only want to set one or more addresses (not names) then you can just
+use the ``setAddresses()`` method instead::
+
+    $to = $message->getHeaders()->get('To');
+    $to->setAddresses([
+      'joe@example.org',
+      'john@example.org',
+      'no-name@example.org'
+    ]);
+
+.. note::
+
+    Both methods will accept the above input format in practice.
+
+If all you want to do is set a single address in the header, you can use a
+string as the input parameter to ``setAddresses()`` and/or
+``setNameAddresses()``::
+
+    $to = $message->getHeaders()->get('To');
+    $to->setAddresses('joe-bloggs@example.org');
+
+When output via ``toString()``, a mailbox header produces something like the
+following::
+
+    $to = $message->getHeaders()->get('To');
+    $to->setNameAddresses([
+      'person1@example.org' => 'Name of Person',
+      'person2@example.org',
+      'person3@example.org' => 'Another Person'
+    ]);
+
+    echo $to->toString();
+
+    /*
+
+    To: Name of Person <person1@example.org>, person2@example.org, Another Person
+     <person3@example.org>
+
+    */
+
+Internationalized domains are automatically converted to IDN encoding::
+
+    $to = $message->getHeaders()->get('To');
+    $to->setAddresses('joe@ëxämple.org');
+
+    echo $to->toString();
+
+    /*
+
+    To: joe@xn--xmple-gra1c.org
+
+    */
+
+ID Headers
+~~~~~~~~~~
+
+ID headers contain identifiers for the entity (or the message). The most
+notable ID header is the Message-ID header on the message itself.
+
+An ID that exists inside an ID header looks more-or-less less like an email
+address. For example, ``<1234955437.499becad62ec2@example.org>``. The part to
+the left of the @ sign is usually unique, based on the current time and some
+random factor. The part on the right is usually a domain name.
+
+Any ID passed to the header's ``setId()`` method absolutely MUST conform to
+this structure, otherwise you'll get an Exception thrown at you by Swift Mailer
+(a ``Swift_RfcComplianceException``). This is to ensure that the generated
+email complies with relevant RFC documents and therefore is less likely to be
+blocked as spam.
+
+It's easy to add a new ID header to a HeaderSet. You do this by calling the
+HeaderSet's ``addIdHeader()`` method::
+
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addIdHeader('Your-Header-Name', '123456.unqiue@example.org');
+
+Changing the value of an existing ID header is done by calling its ``setId()``
+method::
+
+    $msgId = $message->getHeaders()->get('Message-ID');
+    $msgId->setId(time() . '.' . uniqid('thing') . '@example.org');
+
+When output via ``toString()``, an ID header produces something like the
+following::
+
+    $msgId = $message->getHeaders()->get('Message-ID');
+    echo $msgId->toString();
+
+    /*
+
+    Message-ID: <1234955437.499becad62ec2@example.org>
+
+    */
+
+Path Headers
+~~~~~~~~~~~~
+
+Path headers are like very-restricted mailbox headers. They contain a single
+email address with no associated name. The Return-Path header of a message is a
+path header.
+
+You add a new path header to a HeaderSet by calling the HeaderSet's
+``addPathHeader()`` method::
+
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addPathHeader('Your-Header-Name', 'person@example.org');
+
+Changing the value of an existing path header is done by calling its
+``setAddress()`` method::
+
+    $return = $message->getHeaders()->get('Return-Path');
+    $return->setAddress('my-address@example.org');
+
+When output via ``toString()``, a path header produces something like the
+following::
+
+    $return = $message->getHeaders()->get('Return-Path');
+    $return->setAddress('person@example.org');
+    echo $return->toString();
+
+    /*
+
+    Return-Path: <person@example.org>
+
+    */
+
+Header Operations
+-----------------
+
+Working with the headers in a message involves knowing how to use the methods
+on the HeaderSet and on the individual Headers within the HeaderSet.
+
+Adding new Headers
+~~~~~~~~~~~~~~~~~~
+
+New headers can be added to the HeaderSet by using one of the provided
+``add..Header()`` methods.
+
+The added header will appear in the message when it is sent::
+
+    // Adding a custom header to a message
+    $message = new Swift_Message();
+    $headers = $message->getHeaders();
+    $headers->addTextHeader('X-Mine', 'something here');
+
+    // Adding a custom header to an attachment
+    $attachment = Swift_Attachment::fromPath('/path/to/doc.pdf');
+    $attachment->getHeaders()->addDateHeader('X-Created-Time', time());
+
+Retrieving Headers
+~~~~~~~~~~~~~~~~~~
+
+Headers are retrieved through the HeaderSet's ``get()`` and ``getAll()``
+methods::
+
+    $headers = $message->getHeaders();
+
+    // Get the To: header
+    $toHeader = $headers->get('To');
+
+    // Get all headers named "X-Foo"
+    $fooHeaders = $headers->getAll('X-Foo');
+
+    // Get the second header named "X-Foo"
+    $foo = $headers->get('X-Foo', 1);
+
+    // Get all headers that are present
+    $all = $headers->getAll();
+
+When using ``get()`` a single header is returned that matches the name (case
+insensitive) that is passed to it. When using ``getAll()`` with a header name,
+an array of headers with that name are returned. Calling ``getAll()`` with no
+arguments returns an array of all headers present in the entity.
+
+.. note::
+
+    It's valid for some headers to appear more than once in a message (e.g.
+    the Received header). For this reason ``getAll()`` exists to fetch all
+    headers with a specified name. In addition, ``get()`` accepts an optional
+    numerical index, starting from zero to specify which header you want more
+    specifically.
+
+.. note::
+
+    If you want to modify the contents of the header and you don't know for
+    sure what type of header it is then you may need to check the type by
+    calling its ``getFieldType()`` method.
+
+Check if a Header Exists
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can check if a named header is present in a HeaderSet by calling its
+``has()`` method::
+
+    $headers = $message->getHeaders();
+
+    // Check if the To: header exists
+    if ($headers->has('To')) {
+      echo 'To: exists';
+    }
+
+    // Check if an X-Foo header exists twice (i.e. check for the 2nd one)
+    if ($headers->has('X-Foo', 1)) {
+      echo 'Second X-Foo header exists';
+    }
+
+If the header exists, ``true`` will be returned or ``false`` if not.
+
+.. note::
+
+    It's valid for some headers to appear more than once in a message (e.g.
+    the Received header). For this reason ``has()`` accepts an optional
+    numerical index, starting from zero to specify which header you want to
+    check more specifically.
+
+Removing Headers
+~~~~~~~~~~~~~~~~
+
+Removing a Header from the HeaderSet is done by calling the HeaderSet's
+``remove()`` or ``removeAll()`` methods::
+
+    $headers = $message->getHeaders();
+
+    // Remove the Subject: header
+    $headers->remove('Subject');
+
+    // Remove all X-Foo headers
+    $headers->removeAll('X-Foo');
+
+    // Remove only the second X-Foo header
+    $headers->remove('X-Foo', 1);
+
+When calling ``remove()`` a single header will be removed. When calling
+``removeAll()`` all headers with the given name will be removed. If no headers
+exist with the given name, no errors will occur.
+
+.. note::
+
+    It's valid for some headers to appear more than once in a message (e.g.
+    the Received header). For this reason ``remove()`` accepts an optional

+Modifying a Header's Content
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To change a Header's content you should know what type of header it is and then
+call it's appropriate setter method. All headers also have a
+``setFieldBodyModel()`` method that accepts a mixed parameter and delegates to
+the correct setter::
+
+The header will be updated inside the HeaderSet and the changes will be seen
+when the message is sent::
+
+    $headers = $message->getHeaders();
+
+    // Change the Subject: header
+    $subj = $headers->get('Subject');
+    $subj->setValue('new subject here');
+
+    // Change the To: header
+    $to = $headers->get('To');
+    $to->setNameAddresses([
+      'person@example.org' => 'Person',
+      'thing@example.org'
+    ]);
+
+    // Using the setFieldBodyModel() just delegates to the correct method
+    // So here to calls setNameAddresses()
+    $to->setFieldBodyModel([
+      'person@example.org' => 'Person',
+      'thing@example.org'
+    ]);
